SPECIFICATION forming part of Letters Patent No. 339,257, dated April 6, 1886.

Serial No. 174,290. (No model.)

To @ZZ whom it may concern:

Be it known that I, ALBERT G. Brennerei-r, of Milwaukee, in the county of Milwaukeeand State of Vv'isconsin, have invented new and uset'ul Improvements in Tramways, and I do hereby declare the following to be a t'ull, clear, and exact description of said invention, reference being had t-o the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in tramways for street-cars; and it pertains to that class from which the cars are suspended and operated above the street.

The construction of my invention is eX plained by reference to the accompanying drawings, in which- Figure l represents two tran'iways of my improved form, suspended, respectively, one upon each side o't' the supportingcolumns, from one of which tramways a car is shown suspended. Fig. 2 represents a side view of the same device shown in Fig. l. Fig. 3 is a detail showing an end view of the `journals of the rollers of the car-supporting truck provided with anti-friction roller-bi arings. Fig. 4 is a longitudinal section of the roller and journal-bearings shown in Fig. 3. Fig. 5 rep resents a cross-section of the tramway and one of the supporting-brackets used between the columns and one of the supportiiig-rollers. Fig. 6 is a side view of Fig. 5. Fig. 7 is an enlarged View of one of the side arms which extend outward upon the respective sides ol the columns, in which arm a cross-section of the tramway is shown. Fig. S is a side view ot Fig. 7.

Like parts are represented by the same reference-letters throughout the several views.

Uy tramway and the truck operati ng thereon, consisting of a slotted tube,` A, rollers B,

hangers E F', a-nd a connecting-bar, I), are

substantially the same as shown in the patents for fire-escapes, Nos. 278,310 and 287,410, now owned by myself. Thehangers E E are loosely jitted at their upper ends to the axles ot' the rollers B, from which they are suspended, and they are connected at their lower ends with the respective ends of the car. The two hangers, thus arranged, are connected with each other by the horizontal connecting-bar D. At

quite long distances apart,varying from about a quarter to a half an ordinary city block, 4I erect substantial columns E, which are firmly anchored to the ground, and from their upper ends two outward-extending arms, F F, are provided, ot' such length as will allow the required space for a car to pass upon each side ot' the columns without contact therewith. From these armsFFare suspended my slotted tubular tramways A; but owing to the great space between the columns and arms it beports for the tramway between the columns; and to accomplish this end I provide strong metallic frame-work G G, formed, preferably, of metallic bars and plates, secured together by bolts or ri vets,which frame-work lies edge wise upon the respective other ends of the arms F F, and upon their lower edges are affixed a series of brackets or hangers, H. The brackets H are thus attached at short intervals by bolts, their lower ends being so shaped as to nearly surround the tube, leaving space only between their lower ends for the passage ofthe hangers of the truck. To give greater stability to the fra-mes G G, they are braced or tied together by a rod, I. From the hangers C C rods or bars ot' iron extend either down through the center ofthe car or around it, as shown, and they are ai'iixed at their lowerends to the supporting bed-pieces J I. The car thus suspended may be drawn either by a cable to which motion is communicated by a stationary engine or by any desired motive power. l have, however, shown one form of i device i'or connnunicating motion from a moi tive power within the car, which device consists in aflixing to the tubular support or way a toothed bar, K, (shown in Fig. 8,) in which a toothed wheel, L, is adapted to operate. The wheel L is aliixed to the car, and is coni nected with and rotated by any desired motor, and as the teeth of the rotating wheel traverse the toothed bar within the stationary support ing-way the car is caused to move forward. I do not, however, desire to limit myself to the peculiar form of motor used, as other forms of driving machinery may be employed.

l Having thus described my invention, what l I claim as new, and desire to secure by Letters i Patent, is-

l l. The combination, with a series of supcomes necessary to provide for additional supporting-columns, of'a series of supporting side bar, K, and with a ear suspended by rollers 15 arms extending outwardly from said columns, and hangers from said tubular tramway, of a a metallic framework resting upon the outer toothed wheeLL, operating in said toothed ends of said arms and extending from one arm bar and adapted to be operated by a motive 5 to another, aslotted tubular tramway, aseries power Within said car,whereby the ear is proof hangers or brackets securing said tramway pelled along said way, substantially as set 2o to said metal frame work, a truck consisting forth. of rollers and hangers connected together, and In testimony whereof I affix my signature a ear suspended from said truck, operatingin in presence of two Witnesses.

Io said tramway,substantially as and for the pur- Pose speoied- ALBERT G. BIERBAGH.
